Implement "dmesg -w".
Annoyingly, this means writing a new dmesg implementation that uses /dev/kmsg rather than the klogctl system call. Worse, pre-3.5 kernels don't support that, so we need to keep the old implementation around as long as we still care about those kernels. Since I'm here, add the fancy colors from modern dmesg and the -C flag. Tested on Nexus 9's 3.10 kernel, an Ubuntu 3.13 kernel, and the Nexus One's 2.6.35 kernel.
